Overview
Google Voice is a free phone service that provides a US telephone number, which you select from the available numbers in selected area codes. You can enroll a Google Voice phone number for use with Two-Step Login (Duo), but it should only be considered when all other options are not possible for you.
You can choose to forward text messages and calls to this number to other telephone numbers, or as voice mail messages to your Gmail account or other email account of your choice.
- Google Voice is available only in the US.
- To get a Google Voice number, you will be required to verify an existing US phone number.
- The Google Voice service is not active for Google at IU accounts; you'll need to use a personal Google account to set up Google Voice for Duo.
- Due to security concerns, after enrolling your Google Voice phone number for Two-Step Login (Duo), the University Information Security Office (UISO) recommends that you do not forward your Google Voice phone number to your office phone.
- You should only enroll a Google Voice phone number when all other options are not possible for you.
Two-Step Login options with Google Voice
Google Voice service includes the ability to receive phone calls and SMS messages (text messages), and Two-Step Login (Duo) supports both of these options.
In addition to receiving phone calls and text messages to your Google Voice number, by default the phone calls and text messages will also be forwarded to your Gmail email account.
This means that you can enroll your Google Voice phone number for Duo, and when you need to complete the second step of your login using Duo, you can receive the Duo phone call or text message by accessing your Gmail email account. Since Google Voice service is free, there are no charges for the phone calls or text messages sent by the Duo service.

Duo only allows you to enroll one phone number per authentication method, and using an existing number would prevent you from using Google Voice as a secondary method.
